Hi George,
Are you checking the tuning condenser "in circuit" (connected to the osc. coil)? If so, the trimmer condenser marked 23 on the schematic (Between the osc. coil and ground) is shorted or very leaky. Check C18 also. If out of circuit, then the trimmer (labeled 27 on the schematic) that is part of the tuning condenser may be shorted or very leaky. The plates of the tuning condenser develop corrosion that are almost like "stalactites". These will also short the condenser, however, not when the condenser is set for no plate mesh (Highest frequency on the band you are using). In addition, the resistance reading will usually change drastically when the condenser is rotated between full mesh and no mesh.

In addition to repair and restoration, consider adding a "radio - phono switch". That push pull amp with 42 Tubes will really kick @$$ when fed by an MP3 player or computer playing or streaming big band music or old time radio programs!

Good luck!!
